Global Warming the reason or continuation of global climate changing
Introduction Dozens of hectars with burnt down trees , charred carcasses of birds and animals, smoke-screen which closed the sun for the weeks, it is not a plot of a new film of catastrophies , it is reality which I faced this summer. All this set me thinking about the reasons of natural cataclysms and about what can happen in the near future I think that the reason of this cataclysms is the global warming which is the most readable lately so I decided to do a close study of this theme. Firefighters from Jaroslavl are trying to put out the fire near the village Ostrovo of Orehovo-Zuevo district,Moscow region.In the short the fire is within 50 meters from the village. August,5,2010 Helicopter No 32 Moscow region aviation centre is prepearing to drop water on the forest fire near the village Ostrovo Orehovo-Zuevo district. Global warming – what’s that? Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Most of the observed temperature increase since the middle of the 20th century has been caused by increasing concentrations of greenhouse gases, which result from human activity such as the burning of fossil fuel and deforestation. Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the 21st century. . An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects include changes in the frequency and intensity of extreme weather events, species extinctions, and changes in agricultural yields. Warming and related changes will vary from region to region around the globe, though the nature of these regional variations is uncertain. As a result of contemporary increases in atmospheric carbon dioxide, the oceans have become more acidic, a result that is predicted to continue. The Kyoto Protocol is aimed at stabilizing greenhouse gas concentration to prevent a "dangerous anthropogenic interference“. As of November 2009, 187 states had signed and ratified the protocol.
